Abstract

The most extensive textile export product and one of the nation's cultural legacies is batik cloth. However, regarding environmental quality, West Java's growing demand for batik production results in garbage contaminating the nearby waterways. The type of dye is where the harmful properties of batik waste originate. With descriptive qualitative methodologies and the Miles and Huberman model, this study intends to explain the various types of dyes used by SMEs producing batik in the batik centre region of the City and Tasikmalaya Regency and their impact for environmental health. The findings revealed that small and medium-sized enterprises (SMEs) engaged in the batik industry in Tasikmalaya City (Cipedes) utilized synthetic dyes such as indigosol, reactive Procion and Remazol, dispersion, and direct (mostly monoazo and diazo). In the meantime, batik artisans at the Tasikmalaya Batik Center (also known as Sukapura batik in Sukaraja) work with reactive Procion and Remazol (diazo), indigosol, jolawe fruit peel (Terminalia bellirica), soga jambal bark (Peltophorum pterocarpum), and tingi as natural dyes (Ceriops condolleana). The impact of used the different azo dyes can change the level of pH extremely, also improve the level of BOD, COD, TDS, and heavy metal such as chromium hexavalent ((Cr(VI)) in the waters

Abstract

The vast expanse of seagrass beds in coastal areas can provide many ecosystem services, one of which is the ability of seagrass beds to absorb and store carbon dioxide (CO2). Carbon dioxide gas (CO2) is one of the components of greenhouse gases that contribute to global warming. So the role of seagrass is very important in the ecosystem. This study aims to determine carbon storage in seagrass in the littoral zone of Sancang Beach, Garut Regency, which was carried out in April-June 2022. Determination of potential carbon storage was carried out by taking seagrass samples with a size of 20 cm x 20 cm, then drying to a constant weight. and calculated using a carbon conversion factor for seagrass biomass of 0.34. The results showed that the carbon content at Station 1 Cibako (145.9331 g C/m2) was higher than Station 2 Cikujangjambe (110.026 g C/m2) and Station 3 Ciporeang (117.771 g C/m2). The average carbon content at Sancang beach is 124,577 g C/m2. The conclusion is that in general the carbon storage below the substrate (below ground) in seagrass in the Litoral Zone of Sancang Beach has a greater value than the value of carbon storage above the substrate (above ground).

Abstract

The purpose of this study is to describe an ethnobotanical study of the use of spices based on local wisdom in the Sundanese people in Gununggede Village, Kawalu District, Tasikmalaya City. This research method was carried out in a qualitative descriptive manner with semi-structured observation and interview techniques. The selection of respondents using purposive snowball sampling method and obtained the number of respondents as many as 20. The results showed 31 types of plants belonging to 17 families. Zingiberaceae is the most common family with 6 species. The results of the analysis use the cultural significance index (ICS). The results showed that the highest ICS value was 30 for shallots (Allium cepa) and garlic (Allium sativum) and the lowest 9 for chili bendol (Capsicum chinense) and vegetable starfruit (Averrhoa bilimbi). The results of this study can be concluded that plant species with high ICS values are the species most frequently used and their function cannot be changed in cooking dishes. DOI: http://dx.doi.org/10.23960/jbt.v11.i1.27172

Abstract

Pada saat ini peserta didik menemukan informasi dalam buku teks, internet ataupun persentasi guru dengan berbagai penyajian seperti diagram, grafik, gambar, dan lainnya. Membelajarkan  konsep biologi  tidak hanya dalam bentuk teks namun dapat direpresentasikan secara visual dalam bentuk lain seperti gambar, tabel, grafik salah satunya pada materi sistem eksresi. Multipresentasi atau penyajian dalam berbagai cara sangat penting untuk belajar berkomunikasi. Dalam buku teks, representasi biasanya dalam bentuk gambar, tabel, diagram dan peserta didik harus dapat menginterpretasikannya. Hal ini terkait dengan kemampuan peserta didik dalam penguasaan keterampilan interpretasi dan keterampilan mengomunikasi sebagai salah satu penunjang belajarnya. Tujuan penelitian untuk mengetahui korelasi antara keterampilan interpretasi data dengan keterampilan mengomunikasikan peserta didik pada materi sistem eksresi. Sampel penelitian diambil sebanyak 38 peserta didik. Teknik pengambilan sampel secara purposive sampling. Instrumen penelitian yang digunakan merupakan soal uraian dari indikator keterampilan interpretasi data sebanyak 6 soal dan keterampilan mengomunikasikan sebanyak 5 soal. Pengujian hipotesis menggunakan regresi korelasi bivariat. Sebelum uji hipotesis dengan regresi korelasi bivariat dilakukan terlebih dahulu uji normalitas data dan uji linearitas sebagai uji prasyarat analisis. Hasil penelitian menunjukkan ada hubungan antara keterampilan interpretasi data dengan keterampilan mengomunikasikan (R= 0,456; R2 0,208) artinya terdapat kontribusi keterampilan interpretasi data dengan keterampilan mengomunikasikan sebesar 20,8%.

Abstract

Rendahnya plant awareness peserta didik berpotensi menurunkan kepedulian terhadap tumbuhan dan kelestarian keanekaragaman hayati lokal. Dengan demikian, diperlukan inovasi pembelajaran yang kontekstual dan berbasis masalah guna meningkatkan kesadaran tersebut. Penelitian ini bertujuan untuk meningkatkan plant awareness peserta didik melalui implementasi e-modul interaktif Sundanese edible plants melalui problem-based learning (PBL) pada materi klasifikasi makhluk hidup di kelas X SMAN 2 Kota Tasikmalaya. Penelitian menggunakan quasi-experimental menggunakan rancangan non-equivalent control group design. Penentuan sampel dilakukan dengan purposive sampling sehingga diperoleh dua kelas, masing-masing 31 peserta didik. Instrumen berupa 19 soal pilihan majemuk tervalidasi yang mengukur empat domain plant awareness, yaitu persepsi visual terhadap tumbuhan, kemampuan mengkategorikan tumbuhan sebagai makhluk hidup, pengetahuan tentang tumbuhan, dan sikap terhadap tumbuhan, yang diukur melalui pretest dan posttest. Uji hipotesis menggunakan uji non-parametrik Quade’s Rank Test. Hasil penelitian menunjukkan perbedaan signifikan (Sig. = 0,000 < 0,05) dengan nilai partial eta squared (η²) sebesar 0,224 yang termasuk kategori efek besar. Temuan ini menunjukkan bahwa e-modul interaktif Sundanese edible plants melalui PBL efektif dalam meningkatkan plant awareness peserta didik. Penelitian ini turut berperan dalam pengadaan perangkat pembelajaran yang mengangkat potensi lokal guna mewujudkan edukasi biologi yang relevan serta berorientasi pada pelestarian tumbuhan.

Abstract

Botanical literacy among students remains relatively low, as reflected in recent studies highlighting students’ limited understanding and appreciation of plant diversity and its essential role in ecosystems and human life. This condition underscores the urgency to implement innovative learning strategies to improve students’ botanical literacy. This study aims to analyze the effect of the Project-Based Learning (PjBL) model assisted by Botanipedia media on students’ botanical literacy in plant diversity and classification. As part of biological literacy, botanical literacy includes knowledge, inquiry skills, and the ability to connect plant concepts to real-life contexts. This research applied a quasi-experimental design with a nonequivalent control group. The sample consisted of two Grade X classes at SMA Negeri 2 Tasikmalaya, selected through purposive sampling. Class X-1 (experimental group) was taught using PjBL assisted by Botanipedia, while class X-3 (control group) was taught using PjBL without additional media. Botanical literacy was measured using a 15-item multiple-choice test developed based on Uno and Bybee’s framework. Data were analyzed using Quade Rank Analysis of Covariance. The results showed a significant improvement in the experimental group compared to the control group (p = 0.031, p &lt; 0.05). The integration of Botanipedia enhanced students’ botanical literacy across all indicators. These findings support using interactive media to strengthen botanical literacy through project-based learning.
